Esash Posted March 24, 2018 Share Posted March 24, 2018 I just climbed a pretty big hill on my MCM3 with 50% battery power. Right before the top of the hill I got my first overheat/shutdown warning beep. I immediately got off the wheel and even turned the wheel off for 30 seconds to give it a break. Would I have been fine continuing another 20 yards to the top of the hill, or does the overheat/shutdown warning beep mean that the wheel is about to shut down immediately? Thanks in advance. I'm hoping that if I had continued to ascend the hill slowly, I'd be okay for at least a little bit. Is there a 2nd overheat/shutdown warning beep or just one?

Esash Posted March 24, 2018 Author Share Posted March 24, 2018 2017, KS14C: "I lost my concentration and started accelerating way too hard up a hill. Nothing major (7.3% grade per my GPS tracker) but I was low on battery by that point (showing 4 bars on the EUC and ~55V in the KS app). You can guess what happened next. The thing that surprised me was just how fast the cut-out happened, almost no warning--not what you'd expect from a KS. One second it's all good, the next second I get the sensation that I'm tilting too far forward, and then boom, one beep and the wheel cuts out. I hit the asphalt with my face, literally. Nose bleeding everywhere, vision went white, got faint and dizzy. I staggered to the side of the road and sat there for around 5 minutes until I could see again, then another 10 or so until I could keep my balance on the wheel."

Smoother Posted March 24, 2018 Share Posted March 24, 2018 I think it was the last 20 yards that fried @Jrkline "Wheel Whisperer" 's Monster. He shot past @Marty Backe then moments later he was the proud owner of a 60lb GotWay toaster. You did the right thing. Why risk it to get 20 yards further up the hill. You do Know we call these things HotWays don't you? Rule of thumb for any wheel, if it's hot. GET OFF NOW and let it cool (observe temp reading in app) Link to comment Share on other sites More sharing options...

I'm going to go try that hill again on a full battery. Because I had previously climbed that hill with no beeps, though I might have been going very very slow that time. Thanks again.

When Gotway wheels overheat (>70-degrees Celsius) they tilt-back. Impossible to ride. Did your wheel "beep", or was there a series of beeping? The distinction is important. I believe you were just hearing the 80-percent alarm. When one of my Gotway wheels is in the <25-percent capacity and I then climb any short but steep hill, I will often get a beep because the battery level dropped below 15%. So in your case you were probably OK, but if it kept beeping it might have cut out on you. I don't know how many beeps you were hearing. But yeah, with Gotway, if there are any symptoms of the wheel having difficulty while climbing a steep hill and you are in doubt, it's wise to give it a rest.

It was just one beep, and I thought my battery was around 50% but who knows. I didn't have my new android phone on me. The one I bought based on your advice that I just get a $30 cheapy from Walmart. I'll do more tests with my app running next time. After 3-4 straight winter storms, we're finally getting weather above 30 degrees F. 32 degrees today, lol.

When reporting battery levels it's important to add context - is that 50% under load or 50% while you're standing still. A no-load 50% battery could easily dip below 20% when climbing a steep hill. I'm pretty confident that you were hearing a low battery related beep because your wheel was under heavy load. Link to comment Share on other sites More sharing options...

Interesting, and good to know. Thanks. I guess I should have known that already. Then maybe I would have been fine continuing to ride the last 20 yards, as long as I went slow and listened for another beep. Thanks again Marty!

Smoother Posted March 25, 2018 Share Posted March 25, 2018 All these beeps get confusing, that's why I named my 14c "Lassie" she was always "talking" to me but most of the time I had no idea what she was saying. If you are not sure what alarm you are getting in a given situation, assume the worst, for your wallet and your face, and act accordingly. If you assume you are getting an overheat alarm then act on it. If it was something less destructive, oh well, at least you erred on the side of safety; and you avoided a "my crash" write up. As for this statement: 6 hours ago, Marty Backe said: When Gotway wheels overheat (>70-degrees Celsius) they tilt-back. Impossible to ride. I'm not sure how that jibes with @Jrkline "Wheel Whisperer"'s experience, which Marty caught on film. If you mean it can't be ridden after it overheats, therefore you can't do any damage to it then what happened to JWW? It overheated, he was riding it, and the heat melted the solder of a motor wire, right off the control board. If the statement "impossible to ride" means you can't ride a Gotway wheel to over-heat failure, then I'm confused. Link to comment Share on other sites More sharing options...

The thing about my Monster is that it didn't overheat on that hill.When I have overheated it, then it goes into the swaying mode until it drops below 79C to protect the board.I wish it had overheated that day and went into sway mode,that might have saved the mosfets.I also blew the board in my ACM once.That happened after a long hill climb also but the ACM did go into sway mode just before the mosfet popped.Gotway has a flaw in there board design/software when it comes to popping mosfets.Whereas King Song seems to have not the same issue.I have overheated all my various KS wheels, 18s,16b and 14c, and none of those boards have ever failed.
